This invention relates to improvements in warp'knitting machines of thekind known as Milanese machines, in which a travelling warp is knittedinto a looped fabric. "Its ob- V 5 ject is to provide facilities wherebythe warpinto two or more disthreads can be divided tinct sets, so thatthreads of different thicknesses, as well as threads of different,materials, can be embodied in such fabrics, and lo varying'tensions beput upon the different sets into which the warp-threads are divided. yscribed, entirely new ornamental effectsxcan be produced. l

In a Milanese machine, two' warp-threads are provided in connection witheach needle, that is, one in a front set and another in a rear set, andthe front set travel along the needles in one direction and the rear settravel in the reverse direction- I In order to effect this result,thewarpthreads are wound on a numberof very short Warp-beams, each ofthelatter is mounted in a carriage, and a number of the latter are joinedtogether so as to form an endless chain comprising a front and backsetrextending from one end of the machine to the other joined togetherat the ends so that theycan move round continuously. Thereparethus tworows of travelling warp-beams, one moving in the reverse direction tothe other from which the two sets of threads are drawn, and means areprovided for imparting the requisite travelling movement to this endlesschain of warp-beam carrying carriages. Threads of different materials"or o ferent colours may a system, but owing to the fact that all thethread supplied to the needles must be taken,

from the same set of travellingwarp-beams, it is not possible tointroduce threads of different thicknesses, as winding threads ofdifferent thicknesses side by side on the same present insuperabledifwarp-beam, would to working the threads ficulties when it came offthe same again, naturally build-up quicker when wound on the warp-beam,and consequently overlay an prevent the withdrawal of the finer threads.

According to this invention, each carriage in the endless chain isfitted with two or more short warp-beams, and each of the latter isprovided with independent thread tension mechanism, so that the threadswound on one of -the warp-beams in each carriage, can not only be of adifferent size,

as a less number of threads have to be Wound on each.

The provision of two or more Warp-beams in each travelling carriage asdescribed, will permit of the introduction into the machine of threadsof different sizes, and they can be distributed at any desired intervalThe threads of'each size'are Wound on the correspondingWarp-beams ineach of the carriages A, and as each setotthreads is thus taken from anindependent supply, they can not only be considerably different in size,but the tension on each set can be independently adusted to produce thedesired result, by means of the separate and distinct thread tensionmechanism provided in each case.

As an example of the class of ornamental fabrics Which can be produced,groups of coarser threads than the remainder may be introduced atregular intervals, and as the whole of the threads travelas usual, thecoarser threads form diagonalstripes in the 'worlgbut in addition tothis, the coarser threads. in the front set for the time being formdiagonal stripes which run 111 the rev verse direct-ion to those formedthe coarser threads which are at the time in the rear set, and the saidstripes therefore cross and form a diamond pattern.

The stripes are owing to the coarser thread embodied therein, thickerthan the spaces between them, and where they cross, the fabricis'sti-l-l thicker, and a distinct pattern'is thus formed which isirrespective of colours.

Coloured threads, or different classes of threads which may hesubsequently dyed difierent colours, may however be introduced incombination with the different Sized threads,.thereby affording agreater range of different designs, which can be still further varied byregulating the tension on these threads on one set of warp-beams,relatively to the tension of those on the. other set or sets, wherebydifferent effects can be produced.

W'hatlclaim as my invention and desire to cover by Letters Patent is':-

1. In a Milanese machine, a series of car ria gesoperative'ly connectedtogether for motion one direction, each carriage being provided with aplurality of warp-beams which are moved with it and on which thewarpthreads are distributed in distinct sets.

2; A Milanese machine provided with carriages and Warp-beams as setforth in claim 1,

each warp-beam being provided with a sepa rate thread tensioning device.

3. In a Milanese. machine, a series of carriages operatively connectedtogether for motion in one direction, each carriage having standardssecured to it, and a plurality of warp-beams journaled" in the standardsof each carriage.

4. A Milanese machine as set forth in claim 3', each warp-beam having aseparate thread tensioning device operatively connected with itsjournaL.

'5. In a Milanesemachine, a series of carriages operatively connectedtogether for mo-:

tion in one direction, each carriage beingprovided with a plurality ofwarp-beams which are moved with it, a, thread sley plate supportedbyeach carriage, and a plurality of spring-pressed rollers supportedbyeach car riage and operating to guide the warpthreads to the saids1ey-plate.

In testimony whereof I' have affixed' my.
